Malware is a type of computer program. This name is known to them because they usually annoy the user or cause damage. Any software intentionally designed to harm a computer, server, client, or computer network (in contrast, software that causes unintentional damage due to some defect is usually described as a software bug).

There is a wide variety of malware, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, rootkits, spam, rogue software, and malware.

Programs are also considered malware if they secretly act against the computer user’s interests. For example, at one point, Sony Compact Music CDs silently installed a rootkit on buyers’ computers to prevent illegal copying, but this also increased users’ reported listening habits and inadvertently created additional Security vulnerabilities.

A wide range of antivirus software, firewalls, and other solutions are used to help protect against malware intrusion, detect it if it exists, and recover from malware-related malicious activity.

How to deal with malware threats?

With the rise of malware attacks, attention to viruses, protection against spyware, and protection against malware, programs explicitly designed to combat malware have begun. (Other prevention and recovery measures, such as backup and recovery methods, are listed in the Computer Virus article.)

Antivirus and anti-malware software

A specific component of antivirus and anti-malware software, commonly called an on-the-go or real-time scanner, goes to the kernel or core of the operating System and works similarly to how some malware works. However, work with the user’s informed consent to protect the System.

Whenever the operating System accesses a file, the access scanner checks to see if the file is “legal.” Suppose the scanner detects the file as malware. In that case, the access operation is stopped, and the scanner scans the file in a predefined way (how to configure the antivirus program during installation/upload).

The user will be notified. This may significantly affect the operating System, although the extent to which the scanner is programmed depends. The goal is to stop operations that malware may attempt before operating on the System, including activities that may exploit bugs or cause the operating System to behave unexpectedly. Anti-malware programs can fight malware in two ways:

They can provide real-time protection if malware is installed on your computer.

 This type of malware protection works like antivirus protection because anti-malware software scans all incoming network data for malware and blocks any threats you encounter.

Anti-malware software can only detect and remove malware already installed on your computer. It scans the contents of the Windows registry, operating System files, and programs installed on the computer and provides a list of available threats, allowing the user to choose which files to delete, keep, or compare.

This list lists known malware components by deleting the matching files.

Real-time protection against malware works in the same way as real-time antivirus protection: This software scans disk files at load time and blocks the activity of components known as malware.

Sometimes, attempts to install a startup or modify browser settings may be stopped. Because many components of malware are installed as a result of browser abuse or user error, they use Security software (some of which are anti-malware, although many are not) to “sandbox” browsers (actually downloading the browser from a computer).

And therefore any malware caused by the change) can also be effective in helping to limit any damage. Some viruses turn off System recovery and other essential Windows tools such as Task Manager and Command Prompt.

Hardware implants can be of any type, so there is no general way to diagnose them.

Website Security scan

Some websites provide vulnerability scans because malware damages compromised websites (e.g., by breaking reputations, blocking them in search engines, etc.).
These scans scan the website, detect malware, may detect obsolete software, and report known Security issues.

Air gap network separation

Computers can be protected from malware as a last resort, and infected computers can prevent the release of reliable information by imposing an “air gap” (cutting them off entirely from all other networks).

 However, malware can still penetrate the air gap in some situations. For example, removable media can cause malware problems. Researchers introduced four techniques:
AirHopper, BitWhisper, GSMem, and Fansmitter can leak data from empty computers into the air using electromagnetic, thermal, and acoustic propagation.
